Ringforts, known in Irish as raths, were the most common form of rural settlement in early medieval Ireland, typically enclosing a family farmstead within one or more earthen banks. What makes this example at Curry worth pausing over is the layering of its defences: not one bank but two, separated by a fosse, which is a defensive ditch dug to increase the difficulty of approach and the apparent height of the outer wall.

The interior platform measures roughly 26 metres across its longest axis, defined by an earthen bank between five and six metres wide. On the north-northeast to northeast arc, traces of inner facing-stones are still visible, suggesting the bank was once revetted with stone to hold its shape. The fosse, around six metres across at the top, separates this inner bank from a narrower outer bank, though both the fosse and outer bank now survive only along the south-southeast to west-northwest arc. An entrance is discernible at the east-northeast. A quarry has damaged the platform at the northwest, which accounts for some of the unevenness in that quarter. Roughly 170 metres to the northwest lies a second rath, suggesting this corner of Roscommon once supported a cluster of early medieval activity rather than a single isolated settlement.
